Blasphemy. Pizza is best when served cold the next morning.
This is a very New York/New Jersey perspective. And I respect that your palette is too refined to ever accept a non-fresh bagel.
But there are people who live outside of NY/NJ, who don't have a bagel shop down the street. And you may be surprised to learn that some of us love bagels, and will even eat a toasted bagel. I understand this is an abomination no New Yorker or New Jerseyan would ever touch. But I can assure you many of us with lower standards get quite a bit of joy out of a good re-toasted bagel. If a bagel is sliced and frozen shortly after baking it actually keeps fairly well.
Again, I can't recommend you ever try a toasted bagel yourself. You would certainly be disgusted by it, as any respectable New Yorker would be. But for the rest of us they can be quite enjoyable.
The use case is bagels or pizza across the country? If you don't eat those within the hour they're not good anymore. Other than that, I really can't think of a situation where I would be willing to pay ridiculous amounts of money for cold food.
